Hello,
CAPC includes its own Event Manager data source, however unlike NPC's Event Manager, CAPC's Event Manager is not a Trap Receiver.
So intead of sending the Traps directly to CAPC, set the Trap Destination to the IP address of the NFA Console.
The Harvesters will send traps to the NFA console, and the NFA Console will then sync the Trap Events up to CAPC.
I had posted a tech tip a few months ago at the link below on how to configure this.

Hopefully this will help. You may need to recycle the ReporterAnalyzer Manager Service to update the trap destination address.
You should also do a full recync of the Event Manager data source in CAPC.
